Normally a slave can use chromium_utils.GetActiveMaster() to find
itself and determine which ActiveMaster to use. In that case, the
active master name is passed in as an arg, and we only load the that defines it. When testing, the current "slave"
won't be found. In that case, we don't know which config to use, so
load them all. In either case, masters are assigned as attributes
to the config.Master object.
